Prior research has predominantly examined the role of working memory (WM) in tasks involving numerical information and spatial properties such as memorizing number sequences and performing parity judgment and magnitude comparison. In contrast to focusing solely on the effect of WM on number judgment tasks our study investigates how magnitude-space associations affect WM task performance emphasizing long-term representations specifically the concept of mental number line (MNL) compatibility (small items on the left large items on the right) in long-term memory (LTM). Moving from the idea of representations within LTM contribute to the functioning of WM during task execution we explore the effects of congruent incongruent and negative congruent numerical and non-numerical magnitude–space associations on magnitude-based 1-back (low WM load) and 2-back (high WM load) tasks. MNL compatible n-back and test items are congruent MNL compatible n-back and MNL incompatible (small on the right large on the left) test items (or vice versa) are incongruent and MNL incompatible n-back and test items are considered negative congruent. Because negative congruent and incongruent representations may not activate existing representations in LTM as congruent representations we expected worse WM performance in negative congruent and incongruent trials than in congruent trials. Results reveal that congruent and incongruent representations elicit more accurate and rapid responses than negative congruents suggesting that congruent and incongruent representations contribute to task execution. Additionally we observe a size effect for small numerical magnitudes and a reverse size effect for large physical magnitudes pointing towards the coactivation of LTM and WM in magnitude–space relations. © 2025 Elsevier B.V.

Measuring SNARC Effect: Different Task Setups Reveal Divergent Spatial-Numerical Associations
(Nature Portfolio, 2026-03-16) Bulut, Merve; Haugen, Beria; Dural, Seda; Candemir, Ayşenur; Şefikoğlu, Melike; Çetinkaya, Hakan
Spatial-Numerical Associations (SNAs) reflect the cognitive link between numerical magnitude and spatial orientation. While the SNARC effect, faster-left responses for small numbers and right responses for large ones, is robust in Western populations, findings from Turkish samples have been inconsistent. This study investigated whether methodological factors, including statistical power, sensitivity of measurement, and task setup, contribute to these inconsistencies. Using high-powered, lab-based parity judgment (PJ) and magnitude classification tasks, which are standard task setups when investigating the SNARC effect, as well as a novel Go/No-go (GNG) paradigm with lateralized stimuli and a central response, we examined directional SNAs in Turkish participants. Results revealed a weak reverse SNARC effect in the standard PJ task and a weak left-to-right SNA in the GNG PJ task, but no reliable group-level effects in magnitude tasks. Task setup significantly influenced directional SNA patterns, with opposite effects observed between standard and GNG PJ tasks. These findings suggest that SNAs are context-dependent, with different task setups activating distinct directional SNAs. This highlights the critical importance of methodological design when investigating SNAs.

No SNARC Effect Among Left- to-Right Readers: Evidence From a Turkish Sample
(UNIV ECONOMICS & HUMAN SCIENCES WARSAW, 2023) Merve Bulut; Ilgim Hepdarcan; Ezgi Palaz; Hakan Cetinkaya; Seda Dural; Bulut, Merve; Dural, Seda; Hepdarcan, Ilgim; Palaz, Ezgi; Cetinkaya, Hakan
The spatial-numerical association of response codes (SNARC) refers to the faster left-hand respons- es to smaller numbers and faster right-hand responses to larger numbers. Although easily repli- cable in Western cultures the prevalence of the SNARC effect in other cultures has long been an issue. In the current study we aimed to replicate the SNARC effect in a parity judgement task with Turkish participants (N=66) whose reading habits are entirely left-to-right. The results revealed no SNARC effect. To the best of our knowledge this is the first finding indicating the absence of regu- lar SNARC effect among left-to-right readers in a classical parity judgement task. Based on these findings we suggest that investigations of cultural influences on spatial-numerical associations should take a broader perspective rather than only focusing on reading habits.

Representational Context Modulates the Direction and Transiency of Practice Effects on SNARC
(SAGE Publications Ltd, 2025-09-30) Palaz, Ezgi; Cetinkaya, Hakan; Dural, Seda
The Spatial-Numerical Association of Response Codes (SNARC) effect typically results in faster left-hand responses for small numbers and right-hand responses for large numbers, aligning with the concept of the mental number line (MNL). It is a robust but a flexible phenomenon that can reverse direction depending on the spatial-numerical mappings employed. This study investigates the potential modulatory effects of two contrasting representational contexts (ruler vs. clockface) on the emergence and persistence of the SNARC effect under two opposing spatial-numerical practices (MNL-compatible vs. MNL-incompatible). In Experiment 1, a magnitude classification task was employed as a practice session including either MNL-compatible or MNL-incompatible stimulus-response mappings, and the transfer and transiency of practice effects were examined by engaging participants in three test parity judgment tasks administered 5 min, 1 day, and 1 week after the practice session. In Experiment 2, different representational contexts were introduced during practice sessions. Experiment 2a utilized an image of a ruler as the context consistent with the MNL, while Experiment 2b employed a clockface image as an inconsistent context. Participants underwent testing three times to assess changes in performance over time. Results revealed that MNL-compatible practice effects did not transfer while MNL-incompatible practice effects resulted in a reverse SNARC effect persisting for up to 1 day. However, introducing the ruler context eliminated this transfer, while the clockface context reduced the persistence of the practice effect.

Revisiting the SNARC effect: testing magnitude classification in a Turkish sample typically lacking the SNARC effect

This study investigates the SNARC effect in Turkish participants using a magnitude classification task to examine the roles of semantic influences and cultural experiences. While prior research has shown the absence of the SNARC effect in a parity judgment among Turkish participants who read from left to right our findings further confirm its absence in a magnitude classification task even when semantic demands are minimised. Instead a robust distance effect was observed pointing out the involvement of spatial number processing in the task. These findings are discussed in the context of possible multiple spatial mappings shaped by Turkey's unique cultural and historical background which may hinder the development of a dominant spatial-numerical association. Future research incorporating explicit spatial primes linked to various cultural experiences could clarify the mechanisms underlying the variability of SNARC effects and offer valuable insights into the relationship between cultural history and cognitive processes.

SNARC effect in a transfer paradigm: long-lasting effects of stimulus-response compatibility practices
(SPRINGER HEIDELBERG, 2025-01-18) Merve Bulut; Hakan Cetinkaya; Seda Dural; Bulut, Merve; Dural, Seda; Çetinkaya, Hakan
The Spatial-Numerical Association of Response Codes (SNARC) effect refers to the phenomenon of faster left-hand responses to smaller numbers and faster right-hand responses to larger ones. The current study examined the possible long-lasting effects of magnitude-relevant stimulus-response compatibility (SRC) practices on the SNARC effect in a transfer paradigm. Participants performed a magnitude classification task including either SNARC-compatible or SNARC-incompatible trials as practice. They performed a parity judgment task in the subsequent transfer session administered five minutes one day or a week after the practice session. Results revealed significant SNARC effects after compatible practices and significant reverse SNARC effects after incompatible practices in all time-interval conditions. However a control group without practice showed no reliable SNARC effect. These findings suggest that the SNARC effect can be influenced by magnitude-relevant associations formed a week previously highlighting the long-lasting effects of magnitude-relevant SRC practices on the SNARC effect.

Space-Magnitude Associations Modulate the Familiar-Size Stroop Effect in Visual Size Judgments
(Springer Heidelberg, 2025-11-08) Dural, Seda; Çetinkaya, Hakan; Şefikoğlu, Melike
The familiar-size Stroop effect shows how prior knowledge of an object's real-world size influences visual size judgments, slowing reactions when familiar and visual sizes conflict. This study examined how space-magnitude associations, specifically mental number line (MNL) compatibility, interact with Stroop congruency. Participants compared the visual sizes of two objects, ignoring real-world sizes, and identified either the smaller or the larger object across four conditions: Stroop-congruent/MNL-compatible, Stroop-congruent/MNL-incompatible, Stroop-incongruent/MNL-compatible, and Stroop-incongruent/MNL-incompatible. Tasks followed small-then-large or large-then-small identification sequences. Results showed MNL compatibility modulates Stroop interference: MNL-compatible (small-left, large-right) presentations reduced interference, while MNL-incompatible (large-left, small-right) presentations increased it, depending on task type and order. RT distribution analyses revealed MNL effects emerged in slower bins for Stroop-congruent trials and faster bins for Stroop-incongruent trials within small-then-large sequences. These findings suggest that space-magnitude associations shape the familiar-size Stroop effect, revealing a complex relationship between spatial and conceptual representations in size judgment.
